Aussie Professors Push for $275 / ton Social Cost of CO2

Essay by Eric Worrall

“Health benefits” of CO2 pricing and lower CO2 emissions include having to walk and cycle more.

Australia finally has new climate laws. Now, let’s properly consider the astounding social cost of carbon

The federal government’s climate change bill passed the Senate on Thursday. Among the mandates in the new Climate Change Act are assessments of the social, employment and economic benefits of climate change policies. 

letter we published today in The Lancet Planetary Health outlines the importance of measuring the effects of climate change on human health when assessing the social cost of carbon.

A study this month in Nature put the global social cost of carbon at A$275 per tonne of CO₂ released. Impacts on health (49%) and agriculture (45%) accounted for most of this.

Accounting for the social cost of carbon would lead to investment and policy decisions that support emissions reduction. It would also deter support for projects that increase emissions, such as new coal mines

Australia’s new annual climate change statement should also explicitly examine the health benefits of climate policies. These are likely to include fewer respiratory illnesses as a result of cleaner air, and increases in exercise associated with active travel options such as walking and cycling.

Read more:

I don’t know where the scientists expect solar panels to come from, if they keep deterring coal mines. The only commercial process available today to make silicon for solar panels requires reacting pure silica with vast quantities of coal. This is why the slave factories of Xinjiang are one of the major global centres of solar panel manufacture – Xinjiang has the vast quantities of coal required.

A 49% health benefit from walking or cycling more – what they actually appear to be saying is they will deprive people of choice, to make them healthier. Is this really the kind of world we want, where other people dictate our health choices? Maybe some of us could use more exercise, but if all people really are priced out of their automobiles by carbon taxes, we all know people, or know of people, who would have difficulty cycling everywhere, even if this was the only option. I personally can’t cycle anymore, due to a sport injury.

But the real absurdity of the high social cost of CO2 claim is the claim that global warming would lead to significant agricultural losses. Even NASA admits the world is greening.

Looking to past warm periods, like the Cretaceous (age of the dinosaurs) or the extreme warmth of the Paleocene-Eocene Thermal Maximum, when conditions were so bountiful our primate ancestors spread out from Africa to cover much of Eurasia and the Americas, all the way up to Greenland, the only “evidence” that warmer weather will lead to losses is the broken computer models used to produce such predictions.

The Paleocene-Eocene Thermal maximum, up to 8C / 14F hotter than today, a tropical world of lush abundance stretching all the way to the poles, was not a place where it was difficult to find food.

So where is this great browning, this age of widespread agricultural losses, supposed to fit into a continuum of warming and rising abundance which leads to the tropical garden which was the Paleocene-Eocene thermal maximum?

The NASA observations of greening, and paleo-climate studies of past warm periods, ranging from the Holocene Optimum, the geologically recent period of climatic abundance which allowed our ancestors to abandon the hunter gatherer life, build towns and become farmers, to distant past periods of extreme warmth, like the warm period during which our primate ancestors spread across the world, tell us CO2 and warmth promote plant growth and food plant yields.

Cycling anywhere locally would be a bitch, as the Hill Country of Texas is both hilly and hot.Riding locally would have been an exercise project for me thirty years ago, and no way practical at 66 with a shoulder replacement.
Social cost of carbon calculation involve so many assumptions they are close to POOMA numbers. When changing the discount rate can make a cost a benefit, with the change resulting in a benefit being eminently defensible, SCC is an exhibit number.

An 80 year old regularly cycles through our village in Kent. I have had to rescue him more than once and take him home in the car when he’s toppled off the damn thing.

He’s a liability, wobbling all over the road. He was kicked out the badminton club because he kept collapsing.

Having been involved in improving agricultural yields for over 50 years, I’ve seen many strive for credit. CO2 has never been given its due, and my guess is it’s a least 15 bushel of corn per much is this in $/ton CO2?

When I was born life expectancy in Australia at birth was around 65 years and the CO2 concentration was around 310 ppm, life expectancy is now 83 years with CO2 at around 420 ppm.

What’s worse, is that this increased cost of energy, fuel, and anything that requires either (ie everything), will predominantly affect the poorest in our society. It’s a direct punishment for the poor and disadvantaged.

And where will these taxes end up? In the very pockets of dimwit tax-scrounging ‘scientists’ like these. It’s an absolute travesty of justice. It needs a revolution, French style.

The last 2 years I have dramatically reduced my vehicle costs because I ride just about everywhere now. The city I live in is pretty flat, and the difference in travel time for almost all my trips is bugger all once parking time and traffic is taken into account.

But this is my choice, and should not be foisted on people because of some busy bodies who I suspect will have totally “valid” reasons for not changing from their current ways.

And let’s not forget that people in cars perform monkey acts which cause significant injury to people riding bikes. I’m recovering from a muppet opening a car door on me as I rode past. Luckily I managed to swerve to avoid the car door, but had to hit the car in parked in front of him to avoid hitting moving cars on my right. Were these sorts of incidents included in the study to evaluate the benefits of more pedestrian and riding traffic?

I worked in government policy for many years, for many departments, and the conclusion I came to is that if you put them all together, into one overall picture of society and the individuals in it, it would not add up to a life worth living. Nowhere near. But that’s not a quantitative outcome that can be put into bullet points in an executive summary.

Australia is one of only a handful of countries and the pioneer of laws that punish people of all ages for riding a bike without a helmet.

The 1990-1992 mandatory helmet laws saw a rapid decline in cycling participation of about 30-40%, and that reduction persists on a per capita basis. Over the past decade I’ve seen a grand total of two children riding a bike on my street.

Many countries cite the Australian experience as a reason not to enact all-age helmet laws, which is why 30 years later there’s still only a handful of countries that punish people for getting out of their cars and exercising. Hospitalised injuries per cyclist increased after Australia’s helmet laws were introduced, another reason why other countries avoid such laws.

I might fantasise that Australian politicians could see the logic in repealing helmet laws that discourage cycling and put more people in cars if they want to reduce carbon emissions by 43% in the next eight years.

Sadly, 30 years of disastrous participation and injury data hasn’t convinced them, which is why the idiots will keep the helmet laws despite such legislation increasing cyclist injury risk, damaging public health, increasing traffic congestion and now reducing the odds that their 43% fantasy will be achieved.

“It would also deter support for projects that increase emissions, such as new coal mines”

Do these people live in the real world ?

The IEA say that getting the world to 200m-250m EVs by 2030 will require up to 127 new mines for lithium, nickel and cobalt. There are currently over 1.4 billion ICEVs in the world. Imagine how much more mining will be necessary to replace them all.

All mining creates large amounts of emissions.

September 11, 2022 8:39 am

Pretty much as is the case with the US government, the Australian government and woke climate alarmists there have no idea of what they mean by their attempts to “fight climate change™”.

To wit:
“The report estimates Australia’s total greenhouse gas emissions in the year to December 2021 were 488.0 million tonnes carbon dioxide equivalent”
— Meanwhile, according to the IEA, global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 billion metric tons.

Therefore, if Australia stopped ALL CO2 emissions from ALL sources, it would account for only 0.49/36.6 = .013 = 1.3% of global CO2 emissions into the atmospheric. There you have it, 1.3% tops.

Now, put that 1.3% reduction—accomplished at the expense of devastating the economy of, including exports from, Australia—against the above-stated fact that worldwide CO2 emissions rose 6% in 2021 alone.

But go ahead, tie me kangaroo down, mate, by imposing a “social cost” tax on CO2 emissions.

Since May 17th earth has sequestered 29.3GtCO2 from the atmosphere.
There are concentrations as low as 405ppm areas in like NE Canada, Northern China, Central Africa, eastern amazon and mid-western America.

Carbon dioxide absorbs in water so when it rains concentrations goes down. In summer all the snow has melted and the biosphere greens. In the winter when snow returns the snow consists of carbon which is released back into the atmosphere. Over the snowy lands of Siberia and Russia concentrations tend to be higher than other areas.

By May next year slightly more than 29.3GtCO2 will be put back in the atmosphere.
The $275 is the 29.3Gt nature exchanges as well as the slightly more.

It is corruption like this that makes you sick to the stomach. Earth hasn’t heated up to the 1.2C, so many believe.

But this is part of the deception and fraud governments have committed themselves.
I’m hoping the UK government will do the right thing. So far things are looking promising.
